The v10 setup interacts with the mmu via mmio while the v32 has special regs/insns for accessing the mmu. There might be other difficulties I haven't thought of though. > Too bad. And even if someone would spend the time it looks like it is becoming very difficult to get changes accepted to qemu nowadays. One step at a time ... I would be happy if we can get crisv32 to the point where I can run my automated qemu tests on it with unpatched kernels. Thanks, Guenter
